COIN-OPERATED MECHANISM.

Specification of Letters latent.

Patented Nov. 4,1913.

Application filed November 15, 1911. Seria1 No. 660,508.

To all whom t may concern Be it known that I, PETER VIGGEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Coin-Operated Mechanisms of which the following is a specification.

This invention relates to improvements in coin-operated releasing mechanism to be used in connection with automatic apparatus of various kinds, particularly automatic players or musical instruments of that class in which the pneumatics thereof are operated by means of electricity for the purpose of making or breaking contacts or for starting and stopping the motor which operates the instrument, and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The main object of the invention is to provide coin slot mechanism of the above named general character, which shall be simple and inexpensive in construction, strong, durable and eiicient in operation, and so made as to be operated by the deposit of one or more coins, but is especially intended for the reception of a plurality of coins deposited successively one at a time so that a number of tunes or pieces of music may be played by the instrument or a number of other performances (when not a musical instrument) rendered one after the other, without the necessity of depositing a coin at the end of each tune, or performance.

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In the accompanying drawings illustrating the principle of my invention and the best mode now known to me of applying the principle-Figure l, is a front view partly in section and partly in elevation of a portion of the supporting frame and casing showing parts of the releasing mechanism in their initial positions or out of contact as they will appear when the instrument is at rest, and illustrating diagrammatically the electric connections with the motor and sources of electric supply. Fig. 2, is a similar view of a part or a portion of the supporting frame showing the switch lever in the position it will occupy when contact is made and for starting thc instrument, illustrating by dotted lines the action of the releasing or trip lever. Fig. 3, is a plan view of the base ofthe supporting frame showing it provided with a registering rack and illustrating the controlling or double pneumatic mounted thereon, but with its pawls which engage the rack out of engagement with the latter, which positions they will occupy when the double pneumatic is inlated. Fig. 4, is a similar view of a portion of like parts showing the double pneumatic in its position after the releasing or trip lever has been operated by the deposit of the first and second coins showing said pneumatic partially deiiated and one of its pawls in engagement with the rack and the pneumatic about to register, and by dotted lines as having' registered one tune or performance. Fig. 5, is a view in side elevation partly in section of the supporting frame and a part of the mechanism mounted thereon. Fig. 6, is a fragmental view of the registering rack and double pneumatic showing by dotted lines the positions the parts will occupy on the retreating or receding movement of the double pneumatic just prior to the linishing of the last tune or performance of the instrument, and by continuous lines the position of the parts after the tune or performance of the instrument has been finished and the switch lever has been thrown out of contact, thus bringing the instrument to rest. Fig. 7, is a view in elevation of the top of a partof the double pneumatic and the valve chest showing the conduits connecting the same and those leading to other parts of the instrument, the conduits or tubes connecting the double pneumatic and valve chest being shortened for the convenience of illustration. Fig. 8, is an inner view in elevation of one of the compartments of the valve chest. Fig. t), is a similar View of 'the other compartmentthereof. Fig. l0, is a view in elevation of the opposite side of the compartment of the valve chest shown in Fig. 9, with a portion thereof removed. Fig. 11, is a cross sectional .view taken on line lll-,11, of Fig. 7, looking in the direction indicated by the arrows, and Fig. 12, is a similar view taken on line-l2 12, of Fig. 7, looking in the direction indicated by the arrows.

Like numerals of reference referto corresponding parts throughout the different views of the drawings.

The main or supporting frame for the mechanism which may be secured 'in the automatic instrument at any suitable point, includes an upright portion 15, and a base or horizontally disposed part 16, which is preferably frame -like and segmental in shape as shown in Fig. 3, of thev drawings, and is provided on its upper surface with a series of pins or projections 17, arranged in a row to describe an are of aA circle and to :term a registering rack for cooperation with pawls carried by a duplex or double pneumatic as will be presently explained. The supporting trame is provided at one of its sides with a coin chute 18, for conducting the deposited coins to a suitable receptacle therefor, not shown, and the upper portion of the coin chute 18, is provided with a hopper 19, having a slot 20, in its lower portion, which hopper may have communication with a coin conducting chute, not shown, leading from a suitable point in the casing of the instrument, for admitting coins to the chute 18, for actuating the releasing or trip lever of the mechanism. Mounted on the front surface of the upright part 15, of the frame is a box-like casing 21, which incloses a part of the mechanism and prevents dust from collecting on the same.

Secured to the part 15, within the casing 21, is a bracket 22, in a suitable opening in which is vertically mounted a tube 23, which tube has communication through a flexible conduit or tube 24, with one compartment of the valve chest, the construct-ion and arrangement of which will be hereinafter described. The bracket 22, is provided with two spaced apart dependingr projections 25, and 2G, between which is fulcrumed the releasing or tripping lever 27, which is preferably made of liber and is extended into the chute 18, just belo-w the slot 20, in the hopper 19, of said chute. Mounted on the lever 27, below the lower end of the tube 23, is a valve 28, for said tube which may be made ot felt or other suit-able cushioning material'. This valve is normally held against t-he tube 23, so as to close the same, by means of a spring 29, which is mounted on the fulcrum 30, of the lever 27, and has o-ne of its ends extended under said lever and its other end secured to one ot the depending projections 25, ot the bracket 22, for the tube 23. Pivotally secured at one of its ends to the lever 27, is a substantially U-shaped dog 31, which projects at its other end a slight distance beyond that end of the lever 27, opposite the coin chute and is adapted to engage the upper end ot the switch lever 32, which is fulcrumed on the upright portion 15, of the maintrame. The dog or catch 31, is restricted in its downward movement by means of a stop pin `83, extended transversely through the lever 27, so as'to project on either side thereoic and to provide a stop or rest for the sides of said dog or catch. Secured to the upright part 15, o1l the trame below the lever 27, and within the casing 21, by means ot a bindingr post 311-, is a con.- tact plate 35, which preterably has its tree end forwardly deflected so as to allow the switch lever 32, to pass thereunder and to be held in contact therewith. Connected at one of its ends to the binding gest 3ft, is a conductor 8G, which leads to the motor, 36, for operating the instrument, and has connection through conductors 37 with an electric supply, suoli as a battery 87D, from which the conductors 37 lead. r1`he contact plate 35, and binding post. 841e, is insulated trom the trame 15, by a block 37, oit liber or other insulating material. lilorizontally secured to the part 15, of the trame and within the casing 21, is a guide piece 38, tor the switch lever 32, which guide piece .is preferably made of fiber and provided with a slot. or guideway in one of its ends tor` the reception and operation of the switch lever which is extended through 4an opening 89in the lower part of the casing 21. The tulcrum Zl0, of the switch lever 32, is in the torni ot a. binding post and has connected thereto one end ot an electric conductor 411, which leads to the battery or electric source, tor the instrument, and said tulcrum or binding post is mounted on a block 42, ot ber or other insulating material.

As is clearly shown in Figs. 1, and 5, ot the drawings, the lower end ot' the switch lever 32, is extended to near the base 1G, ot the trame, and has its lower portion twisted as at 43, to present a flatsuriace toward the rear end of a bar 114s, the other end of which is pivotally secured to the front upper portion of the base 1G, of the trame. This bar is limited in its movements by means o1 two stop pins 475, between which the rear portion of said bar is located and which pins project upwardly from the rea portion of the base 1G, near one end ot the rack composed of the pins 17, or upward projections. A soring 4G, secured at one ot its ends to the bar 44, between its ends, and at its other end to the base 1G, is employed to normally hold the bar 4:11-, out of contact with the lower portion of the switch lever 82, which part ot said lever extends into the path ot the bar 114-, when in contact with the plate 35, so that said contact and the lelectric circuit produced through the conductors SG, and 41, may be broken when the bar 1.1, is moved in one direction` by means ot a rod 41st, secured at one ot its ends to the rearlower portion ot the double pneumatic 50, and has its other end projected to fard the bar i-4., in which operation, it is apparent that as the lower portion of the switch lever 82, is

forced by means of the bar 44, from the position vshown by dotted lines in Fig. 1, to that illustrated by continuous lines in said figure, the upper portion of the lever 32, willbe removed from contact with the plate 35, and held out 'of contact therewith by means of the dog 31, on the releasing or trip lever. When the trip lever 27, is tilted by means of a coin 47, it is evident that the dog 31, will be disengaged from the upper end of the switch lever which will again be drawn into contact with the plate 35, by means of a spring 48, secured at one of its ends to a post 49, on the part 15, of the frame, and at its other end to the last named lever between its fulcrum and its upper end.

Pivotally and horizontally mounted on the front portion of the base 16, is a double pneumatic which is designated as a whole b y the reference numeral 50, which consists of a horizontally disposed central portion 51, which is provided on its sides with pneumatics 52, and 53, of the ordinary or any preferred construction which are actuated outwardly at their rear portions from the central .part 51, by means of a spring 54,

' which is Secured at about its middle by means of a screw or pin 55, to the front upper portion of the part 51, of the double pneumatic, and has its ends secured by means of screws or pins 56, to the upper portions of the pneumatics 52, and 53, as will be clearly understood by reference to Figs. 1, and 3, of the drawings. Secured to the rear end of the central portion 51, of the double pneumatic is a downwardly ex- .tended bracket 57, which projects over and rearwardly of the pins 17 which form the registering rack. Secured to the. outer surface of Veach of the pneumatics 52, and 53, and on the lower rearv portions thereof is a horizontally and rearwardly extended arm 58, which projects over the rack pins 17 and each has its free or rear portion downturned as at 59, and provided with a horizontally disposed flattened portion 60, to which flattened po-rtion 60, of the bracket 58, on the pneumatic 52, is pivotally secured near one of its ends a pawl 61, which extends transversely with respect to the rear portion of the double pneumatic and rearwardly of the rack. The flattened portion 60, of the arm 58, on the pneumatic 53, has pivotally secured thereto a pawl 62, which extends transversely `with respect to the double pneumatic rearwardly of the rack and horizontally above or below the pawl 61, carried by the other arm. Each of the pawls 61, and 62, is provided with a cut-away portion 63, and at its inner end with a pointed Vprojection 64, directed toward the pins 17,

or rack. Secured. to each of the pivot pins of each of the pawls 61, and 62, is a spring 65, one end of which engages its pawl outwardly, from the arm` 58, on which it is tively. The partition pivoted while the other end of the spring engages the downturned portion of the arm on which it is mounted. By this arrangement it will be understood that the inner portions of the pawls 61, and 62, will be pressed toward the rack pins 17 but will be prevented engaging the same with their pointed ends 64, by reason of the rearwardly and downwardly projecting bracket- 57, against the rear portion of which the pawls will rest until one or both of the pneumatics 52, and 53, are deflected, when it is apparent that the pawls will be so moved as to cause the bracket 57, to fit in the recesses or cutaway portions 63, of the pawls, thus allowing the pointed ends 64, of the latter to be forced by means of the springs 65, into engagement with the rack, which operation will be performed alternately, as will be hereinafter explained.

Communicating at one of their ends with the pneumatics 52, and 53, are tubes 66, and 67, respectively, which have communication at their other ends with the compartment 68, of a valve-chest 7 O, which may be located at any suitable point within the instrument. The said valve-chest is provided with a partition 71, which divides it into compartments 68, and 69, and said partition has openings 72, and 73, that are closed by means of diaphragms 74, and 75, respec- 71, also has bleed holes 76, leading from one of the compartments to the other. The outer wall of the compartment 68, is provided with ports 77, and 78, which communicate with channels 7 9, and 80, respectively, formed in a block 81, secured to the outer surface of the out-er wall of the compartment 68, which channels lead to the atmosphere. The ports 77, and 78, as well as the adjacent ends thereto, of the channels 79 and 80, are controlled by valves 82, and 83, respectively, each of which has a stem 84, extending through the ports 7 7, and 7 8, and each stem is connected to one end of a bar 85, each of which bars is supported at its other end on a pad 86, secured to the inner surface of the outer wall of the compartment 68, at one side of the port over which the bar is extended. Each of the bars 85, has on its surface and near its end adjacent to its respective diaphragms, a cushion 87, against which said diaphragms will impinge when suificient suction is created in the compartment 68, through the medium of a tube 88, and a bellows or power pneumatic, (not shown) of the instrument to which bellows said tube leads. Communicating at one of their ends with the ports 77 and 7 8, are conduits 89, and 90, respectively, which are preferably in the floor and wall of the compartment 68, and have communication at their other end with the tubes 66, and 67, respectively, which lead to the double pneumatic as is clearly shown in Fig. 7 municating with the compartment G9, of the valve-chest, is a tube 91, which has communication with the tracker-bar (nol shown) of the instrument. TWhen the instrument is at rest all communication from the atmosphere to valve-chest 70, is cnt oli' by means of the valves 28, 82, and 83, and a suction maintained through the tube 88, by means of a bellows or power pneumatic (not shown) which will cause the parts to assume the positions shown in full lines in Figs. 11, and 12, of the drawings.

The operation of the device is as follows: Assuming that the instrument is at rest and the parts are in the initial or starting positions shown by continuous lines in Figs. 1, and 3, of the drawings, it will be understood that by depositing a coin or coins in the chute or hopper, they will pass successively through the slot 20, of said hopper, in which operation the trip lever 27, will be actuated or tilted thereby, one time for each coin. As the lever 27, is tilted, by the deposit of the first coin, from the position shown by continuous lines in Fig. 1, to that indicated by dotted lines in Fig. 2, it is evident Ithat the dog 31, will be raised out of engagement with the switch lever 32, which will be thrown by means of `the spring 48, into contact with the contact plate 55, thus completing the electric circuit between. the conductors 36, and 111, thereby starting the motor which operates the instrument. As the trip lever 27, is depressed by the lirst coin, valve 28, is opened admitting` the atmosphere, which, flowing through tubes :23, and 2st, into compartment 69, of the valvechest 70, forces the diaphragm 75, into contact. with the cushion 87, on the valve stem 84, of t-he valve 82, thereby moving said valve so as to close the inner end of the conduit 79, cutting oit the atmosphere and simultaneously opening the port 77, and allowing air to be exhausted by means of the bellows and tube 88, through the conduit 89, and tube GG, from the pneumatic 52, thus causing deflation, in which operation said pneumatic will fold or close from the dotted position 52a, toward the central portion 51, o1 the double pneumatic 50, see Fig. 11, until the pawl 61, which is attached to the pneumatic 52, by means of the arm 58, shall have moved in a like direction, a suiiicient distance to allow the cut away portion 63, of said pawl to register with the rearwardly projecting bracket 57, thus allowing` the pawl to close inwardly and the pointed projection G4, to contact with the pins 17, as shown in Fig. 4l, in 'full lines, The further movement of the pawl 61, is thus prevented, also the movement of the pneumatic 52, but as the exhaustion of air is still in progress, the free end of the double pneumatic 50 will move in the oppoof the drawings. Com` site direction to that of the lirst movement, until, the air is completely exhausted from the pneumatic 52, when the pneumatic 50 will assume the position shown in dotted lines as at 52", of Fig. 4, the said pneumatic having advanced a suiiicient distance for one operation. lVhen more coins are deposited, a like action takes place for each coin. lVhen the required number of registrations have been made and the instrument is in operation, assuming such instrument to be an automatic player, a selection. will be rendered for each registration. At the end of each selection an opening is provided in the perforated music sheet to correspond with a slot or hole in the tracker bar, (not shown) which communicates with the compartment G9, of the valve-chest 70, by means of the tube 91. wWhile the selection is being rendered, the slot in the tracker-bar is covered by the music sheet as it travels over same, thus closing the tube 91, to the atmosphere, and the pneumatic mechanism will remain at rest. At the end of the selection the opening in the music sheet will register with the hole in the tracker-bar, thus causing atmosphere to enter tube 91, and compartment 69, of the valve-chest 70, force the diaphragm 74E, into contact with the cushion 87, on the valve stem 84, of the valve 83, thereby moving said valve so as to close the inner end of the conduit 80, cutting o the atmosphere and simultaneously opening the port 78, and allowing air to exhaust by means of the bellows (not shown) and tube 88, through the conduit 90, and tube G7, as shown by dotted arrows in Fig. 11, from the pneumatic 53, thus causing deflation. In which operation, re- `terring now to Fig. 6, the said pneumatic will fold or close from the dotted position at 53, toward the center portion 51, of the double pneumatic 50, until the pawl G2, which is attached to the pneumatic 53, by means of the arm 58, shall have moved in a corresponding direction a sufficient dis tance to allow the cut-away portion G3, of said pawl to register with the rearwardly projecting bracket 57, t-hus allowing the pawl to close inwardly and the pointed projection G4, to contact with the pins 17, as shown in full lines in Fig. G. Vhen said contact has been established, the further movement of the pawl is prevented, as is also the movement of the pneumatic 53. .it the stage of the operation, when the player has produced all but the last number of selections for the number of coins deposited the rod or projection 14a. secured to the rear lower central portion of the double pneumatic 50, will be in engagement with the,bar 44k, as shown in dotted lines at 449), and as the exhaustion ot' air is still in progress the free end of the double pneumatic will move in the opposite direction to that of the first movement, until the air -is completely exhausted from the pneumatic 53, when it will assume lthe position shown in full lines in Fig. 6.' The projection 44:3, having caused the bar 4 4-, to move so as to push forward the lower portion of the switch lever 32, causes the circuit through contact plate 35, to Ibe broken, and permits the catch 31, to fall in place in front of said switch lever,

i thus locking same' out of contact until the deposit of a coin. A suitably formed spring 92, secured at one of its ends to the rear centralportion 51, of the double pneumatic, is extended rearwardly to contact with the pins 17, and is employed to prevent the movement of the double pneumatic too freely.
